Proliferated Warfighter Space Architecture (PWSA) Tranche 3 Transport Layer (T3TL) Upsilon DRAFT Solicitation

ID: SDA-SN-25-0007 • Type: Special Notice

Description

Posted: April 25, 2025, 3:20 p.m. EDT

The Space Development Agency (SDA) anticipates soliciting proposals from industry for the Proliferated Warfighter Space Architecture (PWSA) Tranche 3 Transport Layer Upsilon (T3TL ). The T3TL constellation will consist of four (4) orbital planes with ten (10) T3TL SVs in each plane, and the government intends to make two awards of twenty (20) vehicles each. Every T3TL SV will be interoperable with all PWSA SVs, regardless of vendor. The T3TL SVs will include optical communications terminals (OCTs) to support in-plane and cross-plane crosslinks, links to terrestrial OCTs (ground, air, and maritime), and crosslinks to compatible SVs external to the Transport Layer. The T3TL SVs provide TACSATCOM bidirectional communications links with select tactical users worldwide via UHF and S-band communications, as well as Integrated Broadcast Service (IBS) Low Earth Orbit (LEO) (IBS-L) space-based broadcast of threat warning, situational awareness, targeting, and C2 data to warfighters worldwide via UHF communications.

Please see the attached DRAFT solicitation for details.

Instructions for requesting Controlled Unclassified Information (CUI) documents and one-on-one, draft solicitation discussions are provided in the Solicitation Cover Letter.

AMENDMENT: This special notice has been reactivated to notify potential offerors that the final solicitation release is planned for April 2025.

AMENDMENT # 2: Release of the final T3TL Upsilon solicitation will be delayed until SDA receives further budgetary guidance. The Sigma and Lambda T3TL solicitations will also not proceed until further budgetary guidance has been received.

Background
The Space Development Agency (SDA) is seeking proposals for the Proliferated Warfighter Space Architecture (PWSA) Tranche 3 Transport Layer Upsilon (T3TLυ). The goal of this contract is to develop and operate a constellation consisting of 40 T3TLυ satellites (SVs), divided into four orbital planes, with ten SVs in each plane. This initiative aims to enhance tactical communications and situational awareness for warfighters globally through advanced satellite technology.

Work Details
The contractor will be responsible for the following tasks:
1. Develop and deliver two orbital planes of ten T3TLυ SVs each, ensuring interoperability with all PWSA SVs.
2. Integrate Optical Communications Terminals (OCTs) for in-plane and cross-plane crosslinks, as well as links to terrestrial OCTs across ground, air, and maritime platforms.
3. Provide bidirectional communications links via UHF and S-band communications to tactical users worldwide.
4. Conduct Launch and Early Operations (LEOPS), including the Separation/Initialization/Checkout/Orbit Raising (SICO) phase and Functional Acceptance Test (FAT).
5. Ensure operational readiness of the satellites through continuous checkout and commissioning processes at designated Operations Centers located at Grand Forks AFB and Redstone Arsenal.
6. Support operations for up to five years post-transition to Mission Operations, including maintenance and sustainment activities.

Period of Performance
The period of performance will commence upon contract award, with initial launch capability established by September 1, 2028, followed by a year-long monthly launch campaign.

Place of Performance
The primary place of performance will be at the contractor's facilities for development activities. Operational activities will be conducted from the Operations Centers at Grand Forks AFB, North Dakota, and Redstone Arsenal, Alabama.
